	Bug 566348 - g_file_open_tmp uses the wrong g_mkstemp on win32

	* glib/gfileutils.c: Move the binary compatibility versions of
	g_file_test(), g_file_get_contents(), g_mkstemp() and
	g_file_open_tmp() last in the file. Remove the restriction that
	the XXXXXX is last in the template in the binary compatibility
	version of g_mkstemp(). Thanks to Morten Welinder and Jody
	Goldberg.
